I bought 8fun kit from this company. It was more expensive than other companies but they seemed to be professional.
I was very wrong. I paied extra £35 for the toolkit, the toolkit was cheap chines and 4 important tools were missing. I emailed the customer service and they apologized and promised me to send the correct one but they never did.
The battery I ordered supposed to be 13ah. They send me cheap chines battery that seems to be standard and it has no labels at all not for the voltage not the size nothing.
At the end i had to buy some took to install my kit. I am really not happy about Dillenger i paid extra money for absolutely nothing i could buy the exact same kit form Wooshbike much cheaper.
In addition to that every time I email them they take a day or more to reply to my email.
My advice is if you want to buy a kit then avoid Dillenger.
